You are creating a content moderation system for user comments.
Your goal is to censor forbidden words by replacing them with "***".

The function censorComment takes a comment and a forbiddenWord as string.

  1. First, find the position of the forbidden word in the comment using find method.
  2. Make sure the word is actually present in the comment by checking that the position is not -1 before attempting any replacement.
  3. Use replace(start, n, str2) to censor the word:
    • First parameter: the starting position of the forbidden word (pos).
    • Second parameter: the length of the forbidden word forbiddenWord.
    • Third parameter: the string to replace the forbidden word ("***").
  4. Return the modified comment.

Example

censorComment("This movie is stupid", "stupid") β†’ "This movie is ***"
censorComment("I hate bugs in code", "hate") β†’ "I *** bugs in code"
censorComment("What a nice day", "bad") β†’ "What a nice day"
